My code is supposed to show up as a slot machine type background there are images in each lane not activated and when you press spin it randomizes which ones get to be visible and if they are not supposed to be visible they are set as invisible. My problem is when you press spin the images do not show up. When I set them visible normally they do show up. So I believe it to be when i try to set them visible in the if/else statements.

The first problem is how you are using the Random class. If you instantiate it again and again and then call random.nextInt(7), you will always get the same value back (probably 0).
Instead you need to instantiate it ones in constructor and assign it to an instance variable.
The second problem is that nextInt(7) doesn't return an int value between 1 and 7 as you assume, but it returns an int value between 0 and 6.
